CTS B7 A4 FSI Crank Pulley Kit

The CTS Turbo B7 A4 FSI Crank Pulley Kit replaces the factory crankshaft pulley with a precision-machined billet aluminium alternative designed specifically for 2005-2008 Audi B7 A4 FSI engines. This lightweight pulley significantly reduces rotating mass at the crankshaft, allowing the engine to rev more freely whilst improving throttle response throughout the rev range. CNC-machined from aircraft-grade aluminium and hard anodised for durability, the kit includes all necessary hardware for straightforward installation. An intelligent upgrade for workshops seeking measurable drivetrain improvements without compromising accessory drive reliability on naturally aspirated FSI platforms.
